I was surprised to see that the transmitter puts out a whopping 12 mW while the limit is 125 mW.

The output is definitely more.
Here you can see a comparison between Jeti and Hott. Hott seems to have a higher output than Jeti, which is a good full-range system.

Wise words from a man who can't tell polarisation and radiation pattern apart.

The only things that were reduced were Graupner's problems trying to sell radios before they introduced Hott.

It's not physically possible to have a higher output than what is allowed by definition in the FCC test report. So, if the power output is not 12mw, then it is illegal.... period.

I will ask Graupner about this. I can't imagine that they would let these out with a power output higher than specified under their FCC testing. If they did, they would be facing stiff fines and a recall of the product - just like JETI did.

Julez, you MUST be running the European version. The FCC test report clearly shows that 2474MHz is the last frequency allowed, and your RF scanner shows that 2480MHz is being used - well into our (FCC) restricted band edge beginning at 2483.50MHz.

There comes a point where a debate about a manufacturer and their product goes from giving one a positive feeling about a product to negative one. If a discussion gets to that point I no longer think about if the product is good or bad but instead it becomes a controvesial product and I get shy and tend to stay away from it.

I do not think that that was the intent of the OP, but thats how it turned out for me.

Do any of you detractors belive that you are going to change anything about this product by writing here on RCGroups. This gives you permission to rethink.
Add instead forward constructive criticism or praise, something you know something about and not just bull_hit.
... and Jim Drew, have not you your own brand to nurture and protect.

Since I live in the U.S. and belong to the U.S. manufacturers radio committee, we watch things like systems coming in from outside of the U.S. and FCC grants. 12mw is not a robust power output. That is on par with the Chinese R/C toys. Everything else in the U.S. is >= 100mw.

It's not physically possible to have a higher output than what is allowed by definition in the FCC test report. So, if the power output is not 12mw, then it is illegal.... period.

E.g. they claim that their "normal" 2.4 GHz TX antenna has a gain of less then 2db. If it would have a gain of 2 db, then some measurements with the MX-16 show that they would also violate the European limit of 100mW EIRP with their TX's.

Btw: Just visited Graupner's booth at the 1st ProWing exhibition in Germany. Their MX-20 software is not ready and it still has some bugs. But they told me their team of test pilots is working hard to eliminate the bugs....

...But I think this will be in the Software quite soon, Graupner ist starting
from scratch without money.

Viele Gruesse,

Short summery of the report written by PricewaterhouseCoopers about the situation:

Investments and property were sold in November 2010 on the proposed price and liquidity inflows, the banks also have pledged rollover of loans and credit lines at least to June 30th 2012.

On the cost side savings are planned in the areas of personnel and materials as well as other operating expense.

Graupner sold EBAGEC in Ecuador and Balsatec. (Thus, there should be some money to pay the Koreans.)

The positive continuation prognosis and thus the survival of society depends largely on the successful launch of new products, particularly in the area from RC. This is particularly the introduction of newly developed RC-system HoTT (2.4 GHz). The cooperation with suppliers to solve the problems in remote control technology is a top priority.
(The Korean development of the new Hott radios goes back into late 2009/early 2010.)
